多媒体技术能够把抽象的数学知识形象、具体地显现出来,便于学生理解和掌握。在小学数学教学过程中,积极引导学生积累丰富的几何图形经验,培养完善的空间观念,对于小学生打好数学学习基础是至关重要的。这就要求教师必须从学生的认知特点出发,遵循形象思维的发展规律,给学生提供大量鲜活、生动的教学资源,而多媒体可以为实现这样的教学目标提供保障。一、丰富学生的空间认知空间认知是指关于物体、图形的形状、大小及距离、方位等位置关系的知觉。
Multimedia technology can abstract the mathematical knowledge image, specifically to show, for students to understand and master. In primary school mathematics teaching process, actively guide students to accumulate rich experience in geometry and training to improve the concept of space for primary school students to lay the foundation for mathematics learning is essential. This requires that teachers must start from the cognitive characteristics of students and follow the law of development of image-based thinking to provide students with a large number of fresh and vivid teaching resources, and multimedia can provide the guarantee for the realization of such teaching objectives. First, to enrich students’ spatial cognition Spatial cognition refers to the perception of the positional relationship between objects, shape, size, distance, orientation and so on.
